Abstract
The invention discloses a test system of LCD transmittance based on the remote control of a computer. The test system of the LCD transmittance based on the remote control of the computer comprises a detection terminal which is mounted on a production line producing LCD screens and is used for detecting LCD light-transmittance information, and a PC monitoring terminal for receiving data information transmitted by the detection terminal and controlling the detection terminal to work, wherein the detection terminal comprises an LCD driving circuit for driving LCD screens to generate optical-signal information, a data processing unit for acquiring optical signals generated by the LCD screens and processing the optical signals, and a wireless communication module for receiving data information transmitted by the data processing unit and transmitting the data information to the PC monitoring terminal in a wireless communication manner.
Description
Technical field
The present invention relates to a kind of LCD transmission measurement system based on computer long-distance control.
Background technology
LCD liquid crystal display is the display electronic equipment of a planar ultra-thin, and power consumption is very low, be therefore widely applied in electronic product.Because it is made up of the colour of some or monochrome pixels, therefore we need to detect the indices of liquid crystal display, as a distance and effective area information, optimum resolution and true resolution information, brightness and contrast's data message, the data message such as response time and refreshing frequency to input signal, thus ensure the normal work of liquid crystal display, the especially transmitance information of LCD.But the transmission measurement system of the liquid crystal display of prior art has unicity, still there is underproof product to enter into market although cause carrying out quality testing to the liquid crystal display of just having dispatched from the factory, bring certain impact to the prestige of producer.
Summary of the invention
According to prior art Problems existing, the invention discloses a kind of LCD transmission measurement system based on computer long-distance control, comprise be arranged on production LCD display curtain production line on for detecting the sense terminals of LCD transmittance information, receive the data message that described sense terminals transmits, the PC monitor terminal controlling sense terminals work;
Described sense terminals comprises for driving the LCD driving circuit of LCD display curtain generation light signal information, LCD display curtain generation light signal being carried out to the data processing unit of signal sampling and processing, receiving the data message that described data processing unit transmits, the wireless communication module this data message being sent to PC monitor terminal by communication.
The light signal information that described data processing unit receives the LCD display curtain that described test cell collects calculates its transmittance, contrast and corresponding temporal information.
Described test cell comprises signal gathering unit and signal conversion unit.
Described LCD driving circuit comprises light signal generation module.
LCD transmission measurement system based on computer long-distance control disclosed by the invention, can the very first time to the detection of LCD display curtain transmittance and the calculating that just complete generation, adopt PC monitor terminal to monitor in real time whole testing process.
